Patent number: 12116176Abstract: A cap for a container is made of a material at least part of which is derived from natural fibres. The cap comprises a cup-shaped body having a skirt which extends around an axis and a transversal wall arranged transversally to the axis. A cavity is defined inside the cup-shaped body. The cup-shaped body is delimited by an inner surface facing the cavity and by an outer surface facing the opposite way to the cavity. At least one projecting element projects from a surface of the cup-shaped body selected from either the inner surface or the outer surface. At least one recess is provided at the projecting element on another surface of the cup-shaped body selected from either the outer surface or the inner surface.Type: GrantFiled: July 30, 2021Date of Patent: October 15, 2024Assignee: SACMI COOPERATIVA MECCANICI IMOLA SOCIETA' COOPERATIVAInventors: Fabrizio Pucci, Fiorenzo Parrinello, Giovanni Mazzotti

Patent number: 11492181Abstract: A lug closure includes a central top panel, an annular channel outboard of the top panel, a downwardly extending skirt outboard of the channel, the skirt terminating at an inward curl that defines a curl height, and lugs formed in the curl. Each one of the lugs includes a body that extends radially inwardly from the skirt. The body includes a leading edge that merges into a leading portion of the curl. The leading edge tapers in thickness from the curl height to a minimum lug thickness and forms a leading edge vertical taper angle from horizontal between 6 and 15 degrees. A trailing edge merges into a trailing portion of the curl and the trailing edge tapers in thickness from the curl height to the minimum lug thickness.Type: GrantFiled: June 2, 2020Date of Patent: November 8, 2022Assignee: Crown Packaging Technology, Inc.Inventors: Bart Sims, Galen German

Patent number: 10676250Abstract: A lug closure (10) includes a central top panel (20), an annular channel (30) outboard of the top panel, a downwardly extending skirt (50) outboard of the channel, the skirt terminating at an inward curl (54) that defines a curl height, and lugs (60) formed in the curl. Each one of the lugs includes a body that extends radially inwardly from the skirt. The body includes a leading edge (70a) that merges into a leading portion (80a) of the curl. The leading edge tapers in thickness from the curl height to a minimum lug thickness and forms a leading edge vertical taper angle from horizontal between 6 and 15 degrees. A trailing edge (70b) merges into a trailing portion (80b) of the curl and the trailing edge (70b) tapers in thickness from the curl height to the minimum lug thickness.Type: GrantFiled: August 20, 2015Date of Patent: June 9, 2020Assignee: Crown Packaging Technology, Inc.Inventors: Bart Sims, Galen German

Patent number: 8281945Abstract: Closure system for a container including a cap and a ring adapted to engage by screwing in order to seal the opening, the cap including an upper wall from which in a downwards direction there extends an annular skirt that has a lower annular end and a radially inner surface fitted with a thread. The ring has an annular top rim, an annular collar and a thread complementary to the thread of the cap provided between the collar and the rim of the ring. The skirt of the cap includes a projecting annular member forming a barrier and adapted to be supported against the whole periphery of the collar of the ring in a substantially radial direction.Type: GrantFiled: April 5, 2007Date of Patent: October 9, 2012Assignee: SA des Eaux Minerales d'Evian SAEMEInventors: Michel Roussy, Vincent Loisel

Patent number: 6006933Abstract: A twist-off closure for use with a bottle having a neck, a lip and a ledge surrounding the neck and a plurality of ramp sections. The closure includes a top wall, a skirt and a plurality of tabs extending from the bottom edge of the skirt. The tabs are T-shaped and include a cross arm extending adjacent to the free end of the stem. The cap is made from a steel sheet coated with tin and a varnish or lacquer layer with the edges of the cap being formed by pinch trimming so that a corrosion-resistant layer of tin substantially covers the edges.Type: GrantFiled: April 23, 1998Date of Patent: December 28, 1999Assignee: Product Investment, Inc.Inventors: John C. Henning, Mark E. Melson

Patent number: 5579932Abstract: A tamper-indicating, child resistant closure for a threaded bottle includes an inner cap and an outer driver telescoped over the inner cap. The inner cap includes a top wall having spaced apart upstanding ribs. The outer driver includes a top wall having a pair of top wall segments hinged for pivotal movement to, and being spaced apart from each other by a spacing rib also forming part of the top wall of the driver. Each of the top wall segments initially is secured to contiguous sections of the outer driver by frangible, tamper-indicating tabs, and the top wall segments are moved from a generally horizontal position to a generally vertical position after the tamper-indicating tabs have been broken to form a driving section in the top wall of the driver. This driving section then is directed into the space between the upstanding ribs associated with the top wall of the inner cap by moving the inner cap and outer driver axially toward each other.Type: GrantFiled: June 7, 1995Date of Patent: December 3, 1996Assignee: Lincoln Mold and Dye CorporationInventors: Edward J. Drozd, Vincent Comitini

Patent number: 4392580Abstract: A metal closure cap is described for sealing containers. It is of the lug type having a metal shell with a flowed-in gasket. The cap differs from prior twist caps of this general type by having a tapered corner between the cap top and the cap skirt. This corner design permits a reduced amount of metal to be used and further provides a more rigid closure corner permitting the use of lighter-weight metal. Improved methods of forming the cap shell, including the corner portion are also described.Type: GrantFiled: July 21, 1981Date of Patent: July 12, 1983Assignee: Anchor Hocking CorporationInventor: Charles S. Ochs

Patent number: 4081098Abstract: The disclosure deals with a method of producing round lids with thread-engagement lugs. A round workpiece of rolled sheet metal is deep drawn to form a cup-shaped lid blank with a depending edge portion and during the deep drawing operation the depending edge portion is stamped with spaced finger grips. The finger grips are, seen from the center point of the round workpiece, stamped in four major directions which lie in the rolling direction of the rolled sheet metal and at right angles thereto. The lower edge of the stamped edge portion is then bent to form the finished lid and its thread-engagement lugs.Type: GrantFiled: August 19, 1976Date of Patent: March 28, 1978Assignee: Aktiebolaget Skane-EmballageInventor: Goran Lennart Daniel Johansson
